sudo gem安装后无法访问Jekyll

最初我无法通过此安装gem。sudo gem安装后无法访问Jekyll

$ gem install jekyll 
ERROR: Error installing jekyll: 
invalid gem: package metadata is missing in /usr/local/rvm/gems/ruby-1.9.3-p392/cache/fast-stemmer-1.0.2.gem

然后一些导游推荐使用sudo，所以我使用了

$ sudo gem install jekyll

这说明了安装，但然后......

Successfully installed jekyll-2.5.3 
Parsing documentation for jekyll-2.5.3 
Done installing documentation for jekyll after 1 seconds 
1 gem installed 

$ jekyll -v 

/Users/vincentchin/.rbenv/versions/2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'jekyll' (>= 0) among 105 total gem(s) (Gem::LoadError) 
Checked in 'GEM_PATH=/usr/local/rvm/gems/ruby-1.9.3-p392:/usr/local/rvm/gems/[email protected]', execute `gem env` for more information

from /Users/vincentchin/.rbenv/versions/2.2.2/bin/jekyll:22:in `<main>'

我猜测，通过运行sudo的安装版本，我需要一个不同的命令或路径才能访问该gem？或者，它的安装位置可能无法被任何尝试执行的位置识别？

我查了其他案件，其他人在安装Jekyll时遇到了问题，并且遇到了一些我无法真正理解的研究。所以，如果需要此信息来调查我的问题......

目前运行OS X约塞米蒂10.10.5

你有两个Ruby版本，有一个尝试：

bundle exec jekyll -v

我得到这个错误 '无法找到的Gemfile或.bundle/directory' 我应该删除其中一个版本？我使用RVM，所以我认为这并不重要。 – Vincent

你只需要改变目录到你的应用程序，如果你不是由jekyll创建应用程序，请运行'jekyll new my-awesome-site'，然后'cd my-awesome-site' – pangpang

我卸载了所有的东西（rvm和rbenv），并清理了卸载时没有得到的所有剩余文件，并用ruby重新安装了rvm stable。

从那里我可以使用

gem install jekyll

安装，一切都从那里一帆风顺。

我想在我刚开始的时候，我安装了一堆东西，但不知道它们是干什么的（rbenv和rvm，应该只有两个）。
